  • Patent number: 9308764
    Abstract: A sheet for ink-jet printing including a base sheet 1 and a printing layer 3 formed on a surface of the base sheet 1 and containing a plaster (shikkui) and an organic binder, wherein the printing layer 3, further, contains at least one kind of additive selected from the group consisting of glycerin, water-soluble polymer and non-ionic surfactant. The sheet for ink-jet printing promotes the carbonatation of the plaster (shikkui) after the printing so that the printed image quickly exhibits fastness and weather-proof property due to the carbonatation of the plaster (shikkui).

  • Publication number: 20140234580
    Abstract: A printing sheet 1 comprising a base sheet 5 and an inorganic solidified matter layer 3 laminated on the surface of the base sheet 1, the surface 3a of the inorganic solidified matter layer 3 serving as the printing surface, wherein, in an electron microphotograph magnified by 100 times, the printing surface is a surface on where continuous flat surfaces and indefinite protuberances surrounded by said flat surfaces are present being mixed together, the protuberances being present at a ratio of 10 to 30% per a unit area and being observed having sizes or long diameters of 10 to 300 ?m and in a number of 50 to 300 per 1 mm2. With this printing sheet, the fiber is effectively prevented from adhering on the surface of the inorganic solidified matter layer on which the printing is to be executed, and images can be finely printed maintaining in good quality without being blurred.

  • Publication number: 20090233015
    Abstract: A printing sheet of this invention includes a substrate sheet and a printing layer which is formed on a surface of the substrate sheet and contains a semi-solidified plaster precursor. Printing is effected on the surface of the printing layer by using, for example, an ink-jet printer. Upon effecting the printing by using the printing sheet, a highly durable image can be vividly formed featuring rugged feeling and painting-like deepness.

  • Patent number: 6972840
    Abstract: Optical emission spectra from a test wafer during a plasma process are measured using a spectrometer. The plasma charging voltage retained by (detected by) the test wafer is measured after the process step is completed. The emission spectra are correlated with the plasma charging voltage to identify the species contributing to the plasma charging voltage. The optical emission spectra are monitored in real time to optimize the plasma process to prevent plasma charging damage. The optical emission spectra are also monitored to control the plasma process drift.

  • Patent number: 6806038
    Abstract: A method for forming a conductive trace on a substrate. The conductive trace is patterned with a photoresist mask and etched, thereby forming a polymer layer on a top surface and sidewalls of the photoresist mask and on sidewalls of the conductive trace. The polymer layer contains entrained chlorine gas. The substrate is heated on a chuck in a reaction chamber. A remote plasma is generated from ammonia gas and oxygen gas. The substrate is contacted with the ammonia and oxygen plasma, thereby withdrawing a substantial portion of the entrained chlorine gas from the polymer layer. A radio frequency potential is applied to the chuck on which the substrate resides, thereby creating a reactive ion etchant from the ammonia and oxygen plasma in the reaction chamber and removing the polymer layer from the top surface of the photoresist mask. The photoresist mask is thus exposed, and then removed in an ashing process.

  • Patent number: 6504533
    Abstract: An image display apparatus capable of displaying an image signal of an unknown type. Characteristics of an input image signal are examined and, based on the examined characteristics, an attempt is made to identify the input signal as one of a known type. When the input signal can be identified as one of a known type, the signal is converted into a form suitable for display based on retrieved parameters corresponding to the signal's type. When the input signal can not be identified as one of a known type, the number of vertical lines in the signal is multiplied by a predetermined constant and the resulting product is used to convert the signal into a form suitable for display.
